Specification ofjLetters-BatentNo, 5,478,79gjdated0ctober for the Sidesof Vessels and for other Purposes, of which the following isa full,clear, and exact description, reference being. had to the annexeddrawings of the same, making part of this specication, in which- Figurel is a view of the inner side of the apparatus applied to a detachedportion of the side of a vessel.

Fig. 2 is a section taken vertically through the apparatus, the guarddoor and glassframe being opened for the purpose of ventilation. Fig. 3is a transverse sectional view showing the manner of fastening the glassframe by means of a lever and inclined plane.

The same letters indicate the same parts in all the figures.

The glass lights in the sides and stern of a ship are usually mounted inframes which are secured to the casing of apertures for the admission oflight and air into the hold, which frames open and shut von hinges inorder that they may perform the double oilice of windows andventilators. Heretofore it has been found exceedinglydiiiicult to makethe joint between the hinged frame and the casing perfectly water-tightand cases are by no means uncommon where the leakage has been soconsiderable as to damage the cargo and even to endanger the safety ofthe vessel itself. To prevent the 'recurrence of such accidents as theseis the object of my present invention which I accomplish by very simplebut effectual means. which consist in providing a permanently elasticand durable seat around the casing of the aperture for the hinged glassframe to shut against; this elastic seat or cushion I form by making agroove in the casing which is creased on the sides, and then lling thesame heaping full of strips of caoutchouc or gum elastic cut from asheet or web of the prepared article; I then place a flatj ring of metalupon the gtun and clamp it down tight, which compresses it into all thecreases and thoroughly fills every part of the groove; in this state Iplace the casing in an oven heated to three hundred degrees, more orless, of Fahrenheits thermometrical scale and bake the gum until all themoisture and uncombined :volatile matter is evaporated` and thestripsone solid: mass ;A the.A case-is then withdrawn rings are unclampedandthe gum` will be fou-nd tobe sosolidiand so firmly embedded 1n thelgroove that. itcannot be removedl without considerable diicultyff. Thisproc-- ess I call baking-in the gum andv it is very much expedited byclam ing a number of the cases together and baking all of them at thesame time.

more expeditious and equally secure and permanent method of fasteningand compressing the glass frame upon the gum is to employ a lever (mFigs. 1 and 3) hingedl by fromr theA oveny and cooled after which theWhile this baking process does not in any Y B is the casing whichsurrounds the aper- `for shreds are agglutinated together and: formstructons, have no tendency to adhere to one end to the casing, andhaving a notch on its side which projects over the edge of the glassframe and catches upon an inclined plane (n) on the front edge of thesame, which inclined plane it depresses together with the frame as itmoves along over it until it arrives at the top where it enters a curveddepression and remains at rest;` thus,

von the outside of the casing this door is fastened open, or shut, bymeans of a bolt (r) which is slidden into catches or cavities (t t Fig.2)

Having thus described my improved mounting for the glass lights of shipswhat I claim therein as new and desire to secure by Letters Patent, is-

Securing the caoutchouc by baking and compression in the creased grooveof the casing, to form an elastic seat for the glass frame to be shutdown and compressed upon, to make a watertight joint.
